I'm interested in customizing some notepads and keychains for my business. Can you let me know if you offer customization options? It would be great to understand the range of designs, colors, and sizes available for both products. Also, do you provide samples before placing a bulk order? Seeing a physical sample would really help in making a final decision. Looking forward to your reply!
